Floor & balcony waterproofing in Aldarb: the local context

Aldarb is about 18.7 km from the sea coast (OpenStreetMap). The centre of Aldarb sits about 79 m above sea level (SRTM open elevation data).

Does a warehouse floor or balcony in Aldarb really need waterproofing, given how far it is from the coast? Aldarb's centre sits about 79 m above sea level (SRTM open elevation data), and the town is roughly 18.7 km from the sea coast (OpenStreetMap). That means the site is inland and elevated, but moisture still finds its way into slabs through cracks, poor drainage and aging surfaces. For warehouses, the practical question is which system suits the surface and how much it is likely to cost, and the rates we work from are liquid roof waterproofing at SAR 8–25 per m², epoxy coating at SAR 35–90 per m², and crack injection at SAR 40–120 per metre.

Before any quote is written, a technician walks the floor and balcony areas to map where water sits, where cracks run, and what the current surface is made of. Each crack is measured in metres so the injection work can be priced line by line, and the floor is checked for coating failure, staining and loose sections. Where a balcony or roof edge carries water, the slope and outlets are noted, because a waterproofing layer will only last if water can leave the surface. The findings then decide between options such as bitumen membrane at SAR 15–35 per m², spray foam at SAR 20–45 per m², or XPS boards at SAR 12–30 per m² where insulation is also needed.

To make the visit efficient, have the floor plan or measured drawing of the warehouse and balcony areas ready, along with any previous repair records and a note of where leaks or damp patches have appeared. Clear access to the affected zones, and to any roof or balcony outlets, lets the inspection run without delay. If the warehouse also has a water storage tank, mention it in advance, since internal tank coating is priced separately at SAR 25–60 per m². Having this information on hand means the site visit can focus on the work itself and the quote can follow quickly.

For warehouses, work is phased around operations and stored goods.
